The complex and proprietary nature of geospatial data makes them almost non-sharable among large user community. GIS interoperability is necessary for realizing a successful spatial data infrastructure. With the advancements of web service technology, GIS interoperability has made a paradigm shift – from monolithic GIS providers to distributed geospatial services. The applicability of web servi...

Web-GIS development often forces application domain experts to learn the programming languages and the complex frameworks adopted, thus reducing their productivity As a solution to this issue, we present a visual environment, named WGBuilder, which supports unskilled users in the construction of Web-GIS applications. By performing a set of predefined actions, they specify the customization requ...

Housing market analysts typically rely on Geographic Information Systems (GIS). The new Web Processing Service (WPS) standard proposed by the Open Geospatial Consortium (OGC) offers an alternative that supports desktop GIS analysis functionalities over the Internet via a standardised interface. This article presents how the WPS specification was applied for housing market analyses and demonstra...

This tutorial provides a foundation in GIS including its basic structure, concepts, and spatial analysis. GIS is a new field in business schools and presents opportunities for research. It is derived from about a dozen disciplines, some unfamiliar to most IS researchers. Following an overview of vertical-sector uses of GIS, the paper introduces their costs and benefits. The links of GIS to rela...

'Mashup' was originally used to describe the mixing together of musical tracks to create a new piece of music. The term now refers to Web sites or services that weave data from different sources into a new data source or service. Using a musical metaphor that builds on the origin of the word 'mashup', this paper presents a demonstration "playlist" of four geo-mashup vignettes that make use of a...

Sharing and integrating Remote Sensing (RS) and Geographic Information System/Science (GIS) models are critical for developing practical application systems. Facilitating model sharing and model integration is a problem for model publishers and model users, respectively. To address this problem, a framework based on a Web service for sharing and integrating RS and GIS models is proposed in this...

This paper presents a study on the feasibility, mechanisms and key technology for integrating GIS and OA in the Browser/Server (B/S) architecture, on the basis of a comparative analysis of the independent development model and the integrated development model of GIS and OA. Presently, the development of GIS and OA is mainly based on the two models: Mainframe-Terminal (M -T) model upon stand-alo...

Recent advances in Web-related technologies have significantly promoted the wide sharing and integrated analysis of distributed geospatial data. Geospatial applications often involve diverse sources of data and complex geoprocessing functions. Existing Web-based GIS focuses more on access to distributed geospatial data. In scientific problem solving, the ability to carry out geospatial analysis...
